Problem

Pick lines are inefficiently sorted.

Solutions

More of and ERP-task

Remember. Mobile WMS extends NAV base Warehousing onto the floor and in general does not add functionality

So the creation of the pick document is not a Mobile WMS task.

Organization of Bins, Zones

Besides using Zones and Bins.

NAV Pick Worksheet can use Bin Ranking.

Tip for physical layout

Try to place Popular items

• in close proximity to the beginning of the aisles 
• close to other popular items
  
  

This can be more efficient than focusing on how to dynamically plan a route. But can be overruled by what kind of items you sell, how you replenish, physical space etc. etc.

Seek professional assistance

You need to have this conversation with a dedicated Warehouse consultant, most likely via your NAV Partner.
